Abraham Lincoln

We shall suffer no attachment to literature, no taste for abstract discussion, no love of purely intellectual theories, to seduce us from our devotion to the cause of the oppressed, the down trodden, the insulted and injured masses of our fellow men.

I doubt very much that the chief executives of any of the Fortune 500 corporations can name five edible plants, five native grasses, or five migratory birds within walking distance of their homes, or name the soil series upon which their house sits. And I would contend that if you don't know where you are, you are in fact nowhere at all.
